Ports ZIG/src/lib_vt.zig and terminal/c/* as crates/ghostty-vt-capi (cdylib + staticlib + rlib, soname libghostty-vt.so) implementing the unchanged include/ghostty/vt.h + vt/*.h ABI: OSC parser, SGR parser, key events and key encoding, paste safety, colors, result codes - all 38 native symbols, plus the ghostty_wasm_* helpers on wasm32. Verification: - tests/abi.rs generates a C probe from the headers, compiled with cc, that checks sizeof/alignof/offsetof of every struct/union, every enumerator and #define against Rust, and links every declared symbol; nm -D exports equal the declared functions. - Ghostty's example/c-vt* programs compile unchanged against the Rust library (shared and static) and produce the expected output. - The wasm32 build runs Ghostty's wasm-key-encode/wasm-sgr example scripts unmodified under node (upstream's wasm-sgr tag table is stale vs sgr.h; a regenerated copy checks full output). Test Plan: - cargo test -p ghostty-vt-capi (22 unit + 2 ABI + 5 C + 3 wasm tests)

/** @defgroup key Key Encoding
|
|
*
|
|
* Utilities for encoding key events into terminal escape sequences,
|
|
* supporting both legacy encoding as well as Kitty Keyboard Protocol.
|
|
*
|
|
* ## Basic Usage
|
|
*
|
|
* 1. Create an encoder instance with ghostty_key_encoder_new()
|
|
* 2. Configure encoder options with ghostty_key_encoder_setopt().
|
|
* 3. For each key event:
|
|
* - Create a key event with ghostty_key_event_new()
|
|
* - Set event properties (action, key, modifiers, etc.)
|
|
* - Encode with ghostty_key_encoder_encode()
|
|
* - Free the event with ghostty_key_event_free()
|
|
* - Note: You can also reuse the same key event multiple times by
|
|
* changing its properties.
|
|
* 4. Free the encoder with ghostty_key_encoder_free() when done
|
|
*
|
|
* ## Example
|
|
*
|
|
* @code{.c}
|
|
* #include <assert.h>
|
|
* #include <stdio.h>
|
|
* #include <ghostty/vt.h>
|
|
*
|
|
* int main() {
|
|
* // Create encoder
|
|
* GhosttyKeyEncoder encoder;
|
|
* GhosttyResult result = ghostty_key_encoder_new(NULL, &encoder);
|
|
* assert(result == GHOSTTY_SUCCESS);
|
|
*
|
|
* // Enable Kitty keyboard protocol with all features
|
|
* ghostty_key_encoder_setopt(encoder, GHOSTTY_KEY_ENCODER_OPT_KITTY_FLAGS,
|
|
* &(uint8_t){GHOSTTY_KITTY_KEY_ALL});
|
|
*
|
|
* // Create and configure key event for Ctrl+C press
|
|
* GhosttyKeyEvent event;
|
|
* result = ghostty_key_event_new(NULL, &event);
|
|
* assert(result == GHOSTTY_SUCCESS);
|
|
* ghostty_key_event_set_action(event, GHOSTTY_KEY_ACTION_PRESS);
|
|
* ghostty_key_event_set_key(event, GHOSTTY_KEY_C);
|
|
* ghostty_key_event_set_mods(event, GHOSTTY_MODS_CTRL);
|
|
*
|
|
* // Encode the key event
|
|
* char buf[128];
|
|
* size_t written = 0;
|
|
* result = ghostty_key_encoder_encode(encoder, event, buf, sizeof(buf), &written);
|
|
* assert(result == GHOSTTY_SUCCESS);
|
|
*
|
|
* // Use the encoded sequence (e.g., write to terminal)
|
|
* fwrite(buf, 1, written, stdout);
|
|
*
|
|
* // Cleanup
|
|
* ghostty_key_event_free(event);
|
|
* ghostty_key_encoder_free(encoder);
|
|
* return 0;
|
|
* }
|
|
* @endcode
|
|
*
|
|
* For a complete working example, see example/c-vt-key-encode in the
|
|
* repository.
